蜜蜂花粉篮大小和产蜜量

中国蜂业 1988年第1期 40-42页

作者： Charles p.Milne jr. 刘先蜀

测定了一个蜂场中19群西方蜜蜂的季节产蜜量、工蜂蛹重、工蜂成蜂寿命和工蜂花粉篮大小。产蜜量与花粉篮的长度和面积呈显著相关(相关系数分别为r=+0.551,p<0.0145;r=+0.575,p<0.01)。花粉篮面积与寿命呈显著相关(r=+0.687,p<0.0012)。... 详细信息

测定了一个蜂场中19群西方蜜蜂的季节产蜜量、工蜂蛹重、工蜂成蜂寿命和工蜂花粉篮大小。产蜜量与花粉篮的长度和面积呈显著相关(相关系数分别为r=+0.551,ppp<0.0012)。选育花粉篮大的蜜蜂可提高产蜜量,因为可以有较多的花粉带入蜂群,进而可扩大幼虫面积和延长所培育工蜂的寿命。花粉篮面积是影响全年蜂群产蜜量的一个重要因素,特别是在蜂群平均增重较大的几个星期。

A novel layer deletion method is used to experimentally investigate the effect of induced shielding current transmission (ISCT) in the longitudinal direction on the levitation force of a single-domain YBa2Cu3O7?x (YBCO) cylindrical superconductor (?30×7 mm). In the experiment the sample was gradually sliced into two equal sheets, at the middle height along a diameter with 5 mm every step. The experimental results show that the levitation force is closely related with the ISCT in the longitudinal direction. Any layer deletion, even a small piece of layer deletion can reduce the levitation force of the sample. After the whole layer was deleted the levitation force can diminish about 50%. It is also found that the levitation force is directly proportional to the effective factor of surface area, which is equal to the top surface area divided by the total surface area parallel to the top surface of the sample.

This paper presents a novel onboard system called In-Flight Awareness Augmentation System (IFAp>2p>S) to improve flight safety. IFAp>2p>S is designed to semi-automatically (with human supervision) avoid hazards and accidents due to either internal or external causal factors. The requirements were defined in an innovative way using Systems-Theoretic process Analysis (STpA) method and applied next to model the system. IFAp>2p>S increases aircraft awareness regarding both itself and its environment and, at the same time, recognizes platform and operational constraints to act in accordance to predefined decision algorithms. Results are presented through simulations and flight tests using state machines designed to allow the adoption of appropriate actions for the identified hazards. The different decision algorithms are evaluated over as many as possible hazard situations by simulations conducted with software Labview and Xplane flight simulator. Flight tests are performed in a small fixed wing aircraft and make use of a limited version IFAp>2p>S, partially attending identified requirements. Results support the conclusion that IFAp>2p>S is capable of improving flight safety.

A new bimetallic complex containing Zn and La was prepared from a salen ligand possessing methoxyl groups at the 3, 3′-positions. The structural feature is that one of nitrate groups is disordered and displaced between two metal centers. Crystal system: Triclinic space group:p-1, Z=2. a=0.82714(17) nm, b=1.3484(3) (1) nm, and c=1 3898(3) (1) nm, α=79.89(3)°, β=76.67(3)°, and γ=72.43(3)°. V=1 428 6(5) nm3, Dx=1.812 g·cm-3. (Δρ)max=1 510×10-3 enm3, (Δρ)min=-1.503×10-3 enm3. Accordingly, two water molecules occupy the metal centers in the apical positions via the syn-geometry.

Neurodegenerative diseases such as Alzheimer's disease, parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis are a heterogeneous group of debilitating disorders with multifactorial etiologies and pathogeneses that manifest distinct molecular mechanisms and clinical manifestations with abnormal protein dynamics and impaired bioenergetics. Mitochondrial dysfunction is emerging as an important feature in the etiopathogenesis of these age-related neurodegenerative diseases. The prevalence and incidence of these diseases is on the rise with the increasing global population and average lifespan. Although many therapeutic approaches have been tested, there are currently no effective treatment routes for the prevention or cure of these diseases. We present the current status of our knowledge and understanding of the involvement of mitochondrial dysfunction in these diseases and highlight recent advances in novel therapeutic strategies targeting neuronal bioenergetics as potential approach for treating these diseases.
